To all whom it may concern:

TANNER, of New Haven, in the county of NewHaven and State of Connecticut, have invented a new and usefulImprovement in Clamps for Roller- Skates, which improvement is fully setforth in the following specification and accompanying'drawings, inwhichthereby doing away with. the leather straps which are now in use onthat class of skates.

In the drawings, ,A represents the plate, which is to be securedto thewooden foot-rest by screws or their equivalent, through holes a a a-a.Upon the under side of the plate A inclined projections B are formed, toserve as guides for the clamping-pieces C C. The

clamping-pieces are provided at their inner ends with bearings D D,screw-threaded, corresponding to the right and left hand screwthreadedkey E. Upon the center of the plate a roller-skate. It is made from castmetal,

a downwardly-projecting journal, F, is formed as a bearing for thatportion of the key midway between the threaded parts. The clampingpieces 0 C have at their outer ends upward -projections c 0, p ovidedwith a fillet, d,whicl1 add; materially to the strength of that portionof the clamp.

The operation of the clamp is too well known to require description inthis specification.

The clamp as here described and shown in the illustration is an articleby itself, and can be readily adjusted to the wooden foot-rest of 45cheap, and durable, and can be placed upon the market.
